The main drawback of both libertarian and anarcho-capitalist theories is that they do not exist.

There is an economic theory developed by the Austrian school of economics, which took on a relatively cohesive form thanks to Mises. This is praxeology, that is, the theory of human action; catallactics, that is, the theory of exchange; the theory of money, the theory of interventionism, the theory of the business cycle, and so on. The logic of the libertarian doctrine’s presentation is built upon economic theory, and it is used to verify various fantasies regarding the possible structure of society. Austrian economic theory does not provide quantitative forecasts and postulates the fundamental impossibility of doing so, which gives many followers of other schools reason to criticize it for uselessness in this regard.

There is a libertarian legal theory, also known as institutional or sociological. Russian libertarians generally tend to rely on it in their legal constructions, which is not least because it was developed by Vladimir Chetvernin, who is Russian and still alive. In the English-speaking world, natural law theories are more common.

There are various ethical libertarian teachings: some take natural rights as their basis, others derive ethics from the idea of a contract, and some rely on consequentialism—that is, evaluating actions by their consequences. In short, in the field of ethics, libertarians experience considerable fragmentation and instability.

As a result, libertarianism is a rather broad and pluralistic current of thought, which can be seen as both a plus (there is internal discussion, there is development, but there is also agreement on the fundamentals) and a minus (there is no unambiguous opinion on a number of specialized questions, some of which are quite serious—for example, whether an institution such as the state has a right to exist).

Update: after the post was already written, a video with Alexei Tereshchuk was released on SVTV, which deals precisely with similar issues.
